ApplicationOctober 4, 1954, Serial No. 460,290 7 claims. `(ci. 1s1o4.os)

This invention relates to a type casting machine, such as a Linotype, which is equipped with a mouthpiece provided with perforations therealong and recesses adjacent the perforations, which recesses serve as vents. The perforations `may be in one or more rows spaced along the mouthpiece and parallel to an edge thereof. Now, those perforations became clogged with type metal more particularly the dross thereof requiring its removal. The usual procedure has been to employ a suitable hand drill. However, such drill results in the clogged perforations becoming more or less scarred, as well as resulting in shifting of the direction of the perforations so as to throw them out of alignment. Moreover, sometimes a drill will break oi and render its removal difiicult. The perforations may, moreover, become enlarged which is also undesirable. t

One of the` objects of this invention, therefore, is to provide a tool for removing type metal (which will hereafter be referred to as includingmore particularly the dross thereof) from such a mouthpiece in a simple and eiective manner. p

Further objects will appear from the detailed' description illustrating a number ofembodiments of this inven tion. It is to be understood that this invention is suscep tible` of various embodiments within the scope of the appended claims. t l

. eferring to the accompanying drawing, `10 ,designates a mouthpiece which is provided in this embodiment with two rows of perforationsll and with recesses 12 between the perforations. The mouthpiece -is provided with a shoulder 13 extending therealong and it may also be pro vided with a series of channels 14 also forming shoulders. The perforations 11 receive the type metal and the recesses 12 form vents. It is these perforations 11 which in practice become clogged with type metal and it is an object of this invention to provide a tool to remove the same.

Referring to Figures 2-4, 22 designates generally a carrier having a grip 29 and on which is mounted shell 21. On the carrier specifically in the shell is mounted a punch 15 corresponding to the size of the perforations 11, `and which is a perforating punch which operates by ashear-` of the type as those used in drills to grasp a drill, and with the front faces `thereof corresponding `to the inside of the front of the holder. The right end 18 of the holder is internally threaded to receive a threaded part 19, which engages internal threads in the part 18. After the punch has been placed in the holder by screwing the parts 18 and 19 relatively to engage the jaws 17, the punch will be iinnly seated in the jaws. The part 18 may be provided with a recess 20 to receive the rear end of the punch.

The outside shell or tip 21 is arranged to fit over the holder 16 so that the holder and its punch may move in the shell, the end of the shell being provided with a perforation through which the punch 15 passes.V This shell 21 is mounted on the carrier 22 and the shell is provided with a key 23 received in a latterly open key way 38 in the holder so as to support the shell in the position shown in Figure 2. The shell is held in the holder by a set screw 24 which threads into the shell so as to rmly set the same.

An actuator 25 attached to the part 19 has a head 26. The part 19 is also provided with a lock nut 27 so that when the punch is seated in its jaws, the lock nut can be moved to engage the holder 16 to firmly lock it in position. The actuator 25 moves in a bore in the carrier 22 and is retained in any position by a spring 28 bearing against the actuator. The carrier 22 is provided with the pistol grip 29, which is pivoted on the carrier by a bolt 30 so as to be capable of various angular positions with ref spect to the carrier. The carrier itself may be made in machined halves tightly clamped together by bolts 31 and the pistol grip may also be in halves clamped together by the bolt 30. The pistol grip may be provided with a recess 32for receiving spare punches, which Areceptacle may be closed by a cap 33.

'Ihe shell or tip 21 is provided with an edge gauge 34 projecting forwardly therebeyond and spaced from and transversely of the punch. A nder 35 projects forwardly from the end of the shell and is likewise spaced from and transversely of the punch and is spaced angularly from the gauge 34.` The gauge 34 is spaced from the punch a distance from the edge 13 to the irst row of perforations 11. The iinder 35 is spaced from `the punch a distance from one of the recesses 12 to the adjacent perforation. The gauge 34 has a flat face adapted to slidingly engage the edge or shoulder 13 of the mouthpiece, enabling the nder 35 to be positioned at right angles to the edge or shoulder 13` in order to successively enter the recesses 12, so as to successively position the `punch 15 over the perforations 11. A number of interchangeable shells or tips may be provided, one with a gauge 34 spaced from the shoulder 13 to theV irst row of perforations 11 and another a distance to the `second row of perforations. However, the edge gauge 34 may be removable t and secured to the shell or tip by a set screw 36. In this way, one edge gauge may be constructed to provide ,one spacing and another gauge to provide another spacing between the gauge and the punch. t

The operation of the tool is shown in Figures 24, in which the plane of the mouthpiece is shown as vertical, although it usually `is, placed horizontally. The mouth-- piece may, however, be supported either vertically or horizontally on one or more magnets 37 which may be of the permanent type or an electromagnet. t t

`The punch 15 is placed between the jaws 17 in the holder 16 and firmly clamped therein by screwing the part 19 against the jaws and then securing them by; the lock nut 27. This is accomplished by moving Vthe set screw 24 so 'as torelease the shell 21and1 partially rotatf` ing the shell so as to be `free-of the carrier 22, as shown `in Figure 4. The part 18 may then be screwed on the-partV 19while the head 26 is held, 4S0 as to move ,thejaws 137,;

against the part 18 to clamp the punch. The punch is positioned between the jaws so as to extend to the front face of the shell 21 to contact the mouthpiece when the nder 35 engages a recess 12. For additional stability, the right end of the punch may engage the bottom of the conical-recess 20. Y

The parts being now assembled, as in Figure 2, the tool is grasped by the pistol grip, so as to place :the gauge 34 against the shoulder 13 and so as to place the'nder 35 in a recess 12in order to align the punch with the adjacent perforation 11. The head 26 is now struck with a hammer so as to cause the punch to eject the type metal or dross from the perforation 11. This operation may be repeated until all the perforations in a row have been operated upon to remove the type metal ordross therefrom. In order to remove the type metalV or dross from the second row of perforations, anotherl shell 21 or another edge gauge 34 may be employed as .heretofore de cribed;

The employment of the magnet 37 also performs an additional function. It serves to magnetize the mouthpiece so that the tool with its gauges, which are all of a ferrous metal will be firmly held against the mouthpiece. That serves to hold the tool with its gauge 34 slidingly against the shoulder 13 of the mouthpiece, with the finder 35 held at right angles to the shoulder in order to position the punch 15 over the perforations 11. The pistol grip 29 may be positioned for the convenience of the individual operator.

Figures and 6 illustrate another embodiment of this invention. In thisl embodiment, means are provided for operating the actuator 25. For that purpose, thebore in the holder 22 is provided with an annular shoulder 40 against which seats a strong -spring 41 engaging a collar 42 threaded 011 the actuator 25, which in this embodiment is separate from the threaded part 19. The actuator is provided with an extension 43 arranged to engage the part 19. After the tool has been positioned with respect to the mouthpiece, as previously described, the `actuator 25 is drawn back by its head 26 so as to tensiony the spring 41. VUpon release ofthe head, the actuator will be impelled against the part 19 so as to deliver a hammer blow to the holder 16 and the punch therein in order to punch the type metal or dross from the mouthpiece.

In Figure 5, a trigger mechanism is provided for releasing the actuator after it has been tensioned. For that purpose, the collar 42 is arranged to engage a pin 44 which has an enlargement 45 against which bears a spring 46 engaging a perforated lug 47 in the carrier 22. A trigger 48 pivoted at 49 in the carrier has an arm 50 connected with a link 51 passing through a slot 52 in the enlargement 45, and having an incline 53 arranged to enlarge the bottom of the slot. The spring 46 holds the top of the link for sliding engagement with the abutment 56. A spring 54 connects the link with a pin 55 in the holder so as to normally hold the link and trigger in positions to the right of that shown in Figure 5.

The pin 44, while tensioned, will be normally held against one or more convolutions of the spring 41 since the head of the pin may be somewhat rounded. However, when the head 26 is drawn back to tension the spring until the collar 42 passes the pin 44, this pin Will move up in front of the collar so as to hold the spring tensioned. After the tool has been positioned with respect to the headpiece, as previously described, upon operation of the trigger 48, the pin 44 is moved by the incline or cam 53 so as to withdraw the pin 44 from the collar 42, thereby releasing the actuator 25 to strike a hammer blow against the part'19, in order to cause the punch to eject the type metal or dross from the mouthpiece.

In Figure 7, the actuator 25 is operated pneumatically. It is provided with a cupped head or piston 60 moving in a`cy1inder'61 provided in a boreon the carrier 22 which cylinder receives compressed air from a connection 62 to the cylinder. A light spring 63 on the actuator 25 between a shoulder 64 and a collar 65 threaded in thecylinder 61 serves to hold the actuator in the right end posi- .tion, this actuator being movable in the collar 65. A pin 44 similar to that shown in Figures 5 and 6, is held by a like spring 46 in front of the piston and a similar link 66 tensioned by a spring 54 is connected with a trigger 48. The spring 46 holds the top of the link for sliding engagement with the abutment 56. Air pressure being applied to the cylinder 61, after the tool is positioned with respect to the mouthpiece as previously described, uponl manipulation of the triggerY 48 withdrawing the pin 44, air pressure moves the actuator to the left so as to strike a hammer blow against part 19, in order to move the punch to eject the type metal or dross from the mouthpiece.
